Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

Data center connection is one of the most common uses for dark fiber, and it’s all due to growing data needs. You have probably seen graphs of the Internet’s growth and heard claims about how much data moves along it.

When one of the coaches was asked before the “big game” what would be the key to his team’s success, he said, “executing the fundamentals.” While blocking, tackling, passing and catching may work for football, Ohm’s and Kirchhoff’s Laws are fundamental to understanding any power quality issue.

In this power-hungry world, people find it unacceptable to lose their connection to electricity. A backup generator can supply peace of mind, bringing home- or business-owners the emergency power they need.

An estimated 3 percent of every sales dollar in the United States is spent on solving power quality (PQ) problems, according to Christopher Forthaus, senior product manager, test division, Ideal Industries Inc., Sycamore, Ill.

Is Copper Cheaper than Fiber?

Fiber optics is always expected to cost much more than copper cabling. Whatever you look at—cable, terminations, or networking electronics—fiber costs more. So isn’t it obvious that fiber networks are more expensive than copper? Maybe not! There is more to consider before deciding this.
